6. Every year, their company shareholder meeting has celebrities appear and perform for free.

Talk about a star-studded affair. This year, Walmart's shareholder meeting had special appearances by Pharrell Williams, Robin Thicke, and Sarah McLachlan. The company manages to draw in A-list celebrities to their annual meetings. Unlike other events, these stars don't get paid for their appearances. However, they do get compensated for their time in terms of exposure of their paraphernalia (books, CDs, t-shirts, and more) to customers.

7. Every week, Walmart serves 245 million people in their 11,000 stores worldwide.

This is more than Brazil's population of 202 million — that's a lot of shoppers!

8. Walmart has 1,105,739,688 square feet of retail space; that's one and a half times the size of Manhattan.
